Subject: [PATCH RESEND v2] Input: tsc200x-core - Add axis inversion and swapping support
Date:   Thu, 10 Feb 2022 10:48:43 +0100

Since Commit ed7c9870c9bc ("Input: of=5Ftouchscreen - add support for
inverted / swapped axes"), the of=5Ftouchscreen interface supports axis
inverting and swapping through Devicetree properties. Make use of this
feature.
